Why? Because they are all on sale at B and H, and you can save a grand total of $700 on the trio! (sale price should be shown at checkout)

A trio of Canon L lenses

If you’ve become serious about your photography, or are attempting to make the leap to being a pro shooting, you have likely realized that – as painful as it may be to your wallet – you pretty much need all three of these, or at least one or two of them and a slightly cheaper alternative for the others (such as the EF 17-40mm f/4L USM for the wide angle and the EF 70-200 f/4L IS USM version of the 70-200mm).

You can learn more about each of these lenses and the various alternates in my post about the best Canon lenses here.
